How flu spread

Influenza virus is a RNA virus, mainly A, B, C three kinds. As the antigenic characteristics of influenza virus is very unstable and very prone to mutation, so its hard to have a lasting human immunity, rather than a once measles will no longer suffering. In particular, influenza virus, the most toxic, the most prone to mutation, can often cause severe clinical large outbreak. Such as the 1918 flu virus sweeping the world within a few months, resulting in more than 1000 million people died; and if the fifties of the last century have outbreaks of influenza in China.

Influenza incubation period is usually 1-3 days, most contagious early onset, primarily people with respiratory infections. Influenza patients talking, coughing, sneezing, when the virus released into the air surrounded by people who inadvertently inhaling small droplets containing the virus, can be infected. In addition, the exposure route of transmission is one. Such as influenza patients Momobizi again to touch door handles or toys, and healthy children exposed to these things, You Mo’s own nose, eyes, is also the possibility of being infected, especially in kindergartens, schools, and other inhabited places, your child inadvertently there is the possibility of contracting flu among.

Influenza is different from the cold

Influenza and the common cold there are different in the following aspects:

1, cause: influenza caused by influenza viruses, a sudden onset. The common cold can have a variety of pathogens, such as respiratory syncytial virus, rhinovirus, adenovirus, corona virus and parainfluenza viruses and bacteria, mycoplasma, etc. are generally cold in patients with a history of onset gentler.

2, clinical symptoms: the clinical symptoms of influenza, chills, fever, body temperature can quickly rise to 39 ℃ -40 ℃, generalized weakness, back and limb pain, sneezing, nasal congestion, runny nose and other respiratory symptoms, minor or not obvious. The common cold, runny nose, sneezing and other symptoms, systemic symptoms of mild, non-heat or only low heat, generally 3-5 days of recovery.

3, harmful levels: influenza can cause a worldwide outbreak or pandemic, and the common cold does not develop into a pandemic.

Prevention and control of influenza to avoid misunderstanding

Treatment: Antibiotics infusion essentially null and void

All children suffering from influenza, pneumonia and turn into a relatively fast pace, but also more subtle, especially in infants and young children is not easy to detect, so that treatment be timely, the sooner the better. Treatment principles are as follows:

1, the general treatment: children need to isolate a week or until the main symptoms disappear. Bed rest, more water, add a variety of vitamins, to keep the nasopharynx, and oral hygiene, to prevent complications.

2, symptomatic treatment: a high fever and headache in children can be given antipyretics and physical cooling or sedatives, but the disabled children of aspirin to prevent the occurrence of Reye syndrome. High fever, Ou Tuzhe intravenous rehydration may be appropriate. Cough, sputum person to cough, phlegm medicine, Chinese medicine and other heat antidote.

3, anti-viral therapy: neuraminidase inhibitors and ion channel blocker class of influenza virus M2-sensitive. Early drug effect is good.

The treatment of influenza, many parents there are no small errors.

Myth # 1: Many parents felt that, after suffering from flu, “transfusion” definitely a good fast. Thus, in the annual influenza peak period, the major hospitals will be full infusion room. In fact, the so-called “transfusion”, lose most of the “anti-inflammatory drugs” that is anti-bacterial drugs. The flu is caused by influenza virus infection, so antibiotics are ineffective against influenza viral strain. And antibiotic use can also cause liver and kidney function more damage, diarrhea and other adverse consequences.

Myth # 2: Many parents in order not to delay the child’s school, look forward to the day of fever by drug treatment, or weighed down with their children, day two, three, go to the hospital. In fact, this is extremely wrong, and repeated visits to the hospital not only affects the child’s rest, but also increases the chance of cross-infection, but is not conducive to the child illness recovery. At present no medical treatment of influenza virus, a “panacea”, the influenza rehabilitation depends on the body’s self-repair capacity. If your child is suffering from flu, the best cure is to ensure that adequate sleep and nutrition, fever continued 3 to 5 days is normal, but bad fever that day.

Parents in the care their children should note the following: adequate rest and avoid public places to reduce the spread of opportunities; children should be sunny living room, often ventilation to keep the air fresh; allow children to drink boiled water, promoting toxins discharges, and to eat light, digestible, nutritious liquid or semi-liquid diet.

Prevention: vaccination can not sit back and relax

Not suffering from influenza, especially children, susceptible populations, the need for active prevention.

1, vaccine prevention: vaccination for influenza prevention and control of influenza, one of the main measures. Right of influenza vaccination in children may reduce the chance of influenza infection or reduce the flu-like symptoms. However, influenza vaccine is not within the scope of China’s planned immunization, is required by the parents decided to vaccination.

2, drug prevention: Currently, the World Health Organization recommended for prevention or early treatment of the drug Tamiflu, zanamivir, amantadine and rimantadine. The first two belong to the neuraminidase inhibitors, the latter two drugs are amantadine.

Need to be reminded that the issue of prevention of influenza many parents there are still many errors.

Myth # 1: Some parents think that once their children vaccinated with influenza vaccine can prevent flu, cold or at least reduced than before, this argument is actually not correct. In fact, the influenza vaccine can prevent influenza virus, but can not prevent the occurrence of common cold and can only serve to alleviate common cold symptoms and shorten the cold cycle, and so on. So, can not, after vaccination, or a cold, and the effect that the vaccine is poor.

Myth # 2: Another some parents think their children vaccinated as long as the influenza vaccine, you can sit back and relax a lifetime. In fact, because the vaccine formulation is a pandemic strain of the virus in the year on the basis of forecasts made, while the strains of influenza viruses mutate almost every year, so an annual flu vaccine inoculation.

Myth # 3: Misuse Banlangen. Many parents take for granted that Banlangen have anti-viral, and also traditional Chinese medicine, no side effects, so their children with impunity long-term use, so as to prevent influenza. In fact, wrong. Banlangen is not a medicine for the prevention of influenza, but also taking improper digestion can cause allergic and hematopoietic systems, adverse reactions.

Parents should help their children in their daily lives more prevention of influenza. Wash their hands frequently, avoid crowded public places; multi-vitamin supplements, carrots, cauliflower, sweet potatoes and potatoes are all rich in essential nutrients; in the house of some diluted sprinkling of vinegar, can inhibit influenza virus reproduction; normal supervise their children exercise to enhance physical fitness.
